RELATED APPLICATION

This application is a DIV of Ser. No. 10/123,028 (filed Apr. 12, 2002, now U.S. Pat. No. 6,921,497), which application is a CIP of Ser. No. 09/416,720 (filed Oct. 13, 1999, now U.S. Pat. No. 6,572,792).

BACKGROUND OF THE INVENTION

All matter has structure. The structure of matter emanates from the electronic structure of the elements of the periodic table. It is the electronic structure of the elements and the new electronic structures that arise as a consequence of their combination in molecules that define the electronic state and character of matter. It is also the electronic structure that creates the properties identified and associated with elements and the matter that results from their combination and arrangement (e.g., molecules and matter).

Certain combinations of elements give rise to states of matter with particularly desirable properties. For instance, certain states of matter have long-range order, which refers to matter that has repeating aligned chemical, electronic, or structural units. Example of such states of matter include surfactant membranes, crystals such as smectic liquid crystals and liquid crystalline polymers, and magnetic materials.

One means of imparting unique properties to a material involves adding carbon to the material. Depending on the parent material and on the amount of carbon added, carbon may remain dissolved in a material or may precipitate out to form discrete carbon structures.

SUMMARY OF THE INVENTION

The present invention relates to a new composition of matter comprised of ‘p’, ‘d’, and/or ‘f’ atomic orbitals, and a process for making the composition of matter. This new composition of matter can be distinguished by a change in energy, electronic properties, physical properties, and the like. X-ray fluorescence spectroscopy is a preferred method of detecting and distinguishing new compositions of matter. The change in properties can be controlled to be transient, fixed, or adjustable (temporarily permanent) and includes properties such as mechanical, electrical, chemical, thermal, engineering, and physical properties, as well structural character of the composition of matter (e.g., alignment, orientation, order, anisotropy, and the like).

The present invention includes manufactured metals and alloys characterized by the x-ray fluorescence spectrometry plots and elemental abundance tables (obtained from x-ray fluorescence analysis) contained herein.

The present invention is additionally a method of processing a metal or an alloy of metals, comprising the steps of:

-   -   (A.) adding the metal or alloy to a reactor in one or more steps         and melting said metal or alloy;     -   (B.) adding a carbon source to the molten metal or alloy and         dissolving carbon in said molten metal or alloy, followed by         removing the undissolved carbon source;     -   (C.) increasing the temperature of the molten metal or alloy;     -   (D.) varying the temperature of the molten metal or alloy         between two temperatures over one or more cycles;     -   (E.) adding a flow of an inert gas through the molten metal or         alloy;     -   (F.) varying the temperature of the molten metal or alloy         between two temperatures over one or more cycles;     -   (G.) adding a carbon source to the molten metal or alloy and         further dissolving carbon in said molten metal or alloy,         followed by removing the undissolved carbon source;     -   (H.) varying the temperature of the molten metal or alloy         between two temperatures over one or more cycles, wherein the         molten metal or alloy has a greater degree of saturation with         carbon than in Step (F.);     -   (I.) stopping the flow of the inert gas;     -   (J.) varying the temperature of the molten metal or alloy         between two temperatures over one or more cycles, wherein the         molten metal or alloy has a greater degree of saturation with         carbon than in Step (H.) and wherein an inert gas is added as         the temperature is lowered and an inert gas, chosen         independently, is added as the temperature is raised;     -   (K.) varying the temperature of the molten metal or alloy         between two temperatures over one or more cycles, wherein the         molten metal or alloy has a greater degree of saturation with         carbon than in Step (J.) and wherein an inert gas is added as         the temperature is lowered and an inert gas, chosen         independently, is added as the temperature is raised;     -   (L.) stopping the flow of the inert gases;     -   (M.) varying the temperature of the molten metal or alloy         between two temperatures over one or more cycles, wherein the         molten metal or alloy has an equal or greater degree of         saturation with carbon than in Step (K.); and     -   (N.) cooling the molten metal or alloy to room temperature,         thereby obtaining a solidified manufactured metal or alloy.         Steps (D.), (F.), (H.), (J.), (K.), and (L.) of the present         method are commonly referred to as “cycling steps” below. For         purposes of the present invention, carbon “dissolved” in a metal         is defined as carbon that has been solubilized in a molten         metal, adsorbed by a metal, reacted with a metal, or has         otherwise interacted with a metal such that carbon is desorbed         or transferred from a solid carbon source into a molten metal.

In another embodiment, the present invention is a method of processing copper, or other metal or alloy comprising:

-   -   (1.) contacting molten copper or other metal or alloy with a         carbon source;     -   (2.) an iterative cycling process, wherein relative saturation         of copper or other metal or alloy with carbon remains the same         or increases independently with each cycle; and     -   (3.) cooling the molten copper or other metal or alloy to room         temperature, thereby obtaining a solidified manufactured copper         or other metal or alloy.

DETAILED DESCRIPTION OF THE INVENTION

Electromagnetic chemistry is the science that affects the transfer and circulation of energy in many forms when induced by changes in electromagnetic energy. The theory of Electrodynamics of Moving Bodies (Einstein, 1905) mandates that when the electrodynamic components of the material are manipulated, changes in the energy levels within the atomic orbitals must be induced. These changes in the atomic orbitals are the vehicles by which changes in the (material) properties, such as the magnitude and/or the orientation, can occur. Alignment of the electrodynamic component induces effects that may result in significant changes in the underlying material species: (1) alignment of atoms with the resulting directionality of physical properties; (2) alignment of energy levels and the capability to produce harmonics, may establish physical properties conducive for energy transfer; (3) alignment of the electrodynamic component include the opening of pathways for free electron flow, and; (4) alignment of electrodynamic field phase orientation.

The present invention relates to new compositions of matter, referred to herein as “manufactured” metals or alloys of metals. A “manufactured” metal or alloy is a metal or alloy which exhibits a change in electronic structure, such as that seen in a fluid XRF spectrum. The American Heritage College Dictionary, Third Edition defines “fluid” as changing or tending to change.

Metals of the present invention are generally p, d, or f block metals. Metals include transition metals such as Group 3 metals (e.g., scandium, yttrium, lanthanum), Group 4 metals (e.g, titanium, zirconium, hafnium), Group 5 metals (vanadium, niobium, tantalum), Group 6 metals (e.g., chromium, molybdenum, tungsten), Group 7 metals (e.g., manganese, technetium, rhenium), Group 8 metals (e.g., iron, ruthenium, osmium), Group 9 metals (e.g., cobalt, rhodium, iridium), Group 10 metals (nickel, palladium, platinum), Group 11 metals (e.g., copper, silver, gold), and Group 12 metals (e.g., zinc, cadmium, mercury). Metals of the present invention also include alkali metals (e.g., lithium, sodium, potassium, rubidium, cesium) and alkaline earth metals (e.g., beryllium magnesium, calcium, strontium, barium). Additional metals include aluminum, gallium, indium, tin, lead, boron, germanium, arsenic, antimony, tellurium, bismuth, and silicon.

The present invention also includes alloys of metals. Alloys are typically mixtures of metals. Alloys of the present invention can be formed, for example, by melting together two or more of the metals listed above. Preferred alloys include those comprised of copper, gold, and silver; tin, zinc, and lead; tin, sodium, magnesium, and potassium; iron, vanadium, chromium, and manganese; and nickel, tantalum, hafnium, and tungsten.

Carbon sources of the present invention include materials that are partially, primarily, or totally comprised of carbon. Those carbon sources that are non-organic and comprised partially of carbon are primarily comprised of one or more metals. Suitable carbon sources include graphite rods, graphite powder, graphite flakes, flillerenes, diamonds, natural gas, methane, ethane, propane, butane, pentane, cast iron, iron comprising carbon, steel comprising carbon, and combinations thereof. A preferred carbon source is a high purity (<5 ppm impurities) carbon source. Another preferred carbon source is a high purity (<5 ppm impurities) graphite rod. The carbon source is selected, in part, based on the system to which it is added. In one example, graphite rods and graphite flakes are added to copper, typically in a sequential manner. In another example, graphite rods and graphite powder are added to iron, typically in a sequential manner.

Carbon sources can be contacted with molten metals for variable periods of time. The period of time the carbon source is in contact with molten metals is the time between adding the carbon source and removing the undissolved carbon source. The period of time can be from about 0.5 hours to about 12 hours, about 1 hour to about 10 hours, about 2 hours to about 8 hours, about 3 hours to about 6 hours, about 3.5 hours to about 4.5 hours, or about 3.9 hours to about 4.1 hours. Alternatively, the period of time can be from about 5 minutes to about 300 minutes, about 10 minutes to about 200 minutes, about 20 minutes to about 120 minutes, about 30 minutes to about 90 minutes, about 40 minutes to about 80 minutes, about 50 minutes to about 70 minutes, or about 59 minutes to about 61 minutes.

A cycle of the present invention includes a period of time where the temperature and/or the degree to which a metal is saturated with carbon is varied. Over a period of time, varying the temperature involves a period of raising (or increasing) the temperature of a metal or alloy and a period when the temperature of a metal or alloy decreases (either passively, such as by heat transfer to the surrounding environment, or actively, such as by mechanical means), in any order. Inert gas can be added during a cycle, except where it is specified that inert gas addition is ceased prior to that cycle. Increasing the temperature of the metal or alloy increases the amount of carbon that can be dissolved into that metal or alloy, which therefore decreases the degree to which the metal or alloy is saturated with carbon (relative to the temperature and degree of carbon saturation when graphite saturation assemblies are removed the first time). Similarly, decreasing the temperature of the metal or alloy increases the (relative) degree to which the metal or alloy is saturated with carbon.

The degree to which a metal is saturated with carbon varies over the course of a method, as well as within each step. In Examples 1-14, the degree of carbon saturation varies between 70% and 95% in the first cycling step, between 70% and 95% in the second cycling step, between 101% and 103% in the third cycling step, between 104% and 107% in the fourth cycling step, between 108% and 118% in the fifth cycling step, and between 114% and 118% in the sixth cycling step. The cycling steps correspond to Steps (D.), (F.), (H.), (J.), (K.), and (L.), respectively, of the method described in the third paragraph of the summary.

One example of a method of the present invention can be described in terms of carbon saturation values. After a metal or alloy is added to a suitable reactor, establish the dissolved carbon level at 70% to 95% of the equilibrium saturation of carbon for the thermodynamic state specified (e.g., T, P, composition) when the composition is in its natural state (hereinafter the equilibrium saturation of carbon is referred to as “[C]_(eqsat)”). Identify temperature set points for 80% and 95% [C]_(eqsat). Vary the temperature between the predetermined set points, such that the temperature is decreased for 7 minutes and increased over 7 minutes per cycle, for 15 cycles. Next, establish a flow of argon Vary the temperature between the predetermined set points, such that the temperature is decreased for 7 minutes and increased over 7 minutes per cycle, for 5 cycles; the temperature should be maintained above 70% [C]_(eqsat) at all times and maintained below 95% [C]_(eqsat), at all times. The carbon level is raised to saturation (i.e., [C]_(eqsat)) with continued argon addition. Hold for 60 minutes at saturation (i.e., [C]_(eqsat)) with continued argon addition. Raise the carbon level to ⁺1%_(wt) (i.e., ⁺1%_(wt) represents ⁺1%_(wt) above the saturation value as defined in its natural state) of [C]_(eqsat) with continued argon addition and hold for 5 minutes. Vary the temperature for 20 cycles to remain between ⁺1%_(wt) and ⁺3%_(wt) of [C]_(eqsat), such that the temperature is decreased over 9 minutes and increased over 9 minutes per cycle. Cease argon addition. Cool the metal to ⁺4%_(wt) of [C]_(eqsat). Vary the temperature for 4.5 cycles to remain between ⁺4%_(wt) and ⁺7%_(wt) of [C]_(eqsat), such that the temperature is decreased over 3 minutes and increased over 5 minutes. Argon is added as the carbon saturation increases and nitrogen is added as carbon saturation decreases. Cool the metal to obtain ⁺8%_(wt) with continued argon addition. Vary the temperature over 15.5 cycles to remain between ⁺8%_(wt) and ⁺18%_(wt) of [C]_(eqsat), such that the temperature is decreased over 15 minutes and increased over 15 minutes. Argon is added as the carbon saturation increases and nitrogen is added as carbon saturation decreases. After the 15.5 cycles are complete, gas addition is halted. Perform one complete cycle by varying the temperature to remain between ⁺18%_(wt) to ⁺14%_(wt) of [C]_(eqsat) (ending at ⁺18%_(wt)), such that the temperature is increased over 15 minutes and decreased over 15 minutes. Proceed immediately to a cool down that leads to solidification.

An iterative cycle process is a process comprising two or more cycles, whereby one or more of the cycles are carried out at a temperature below the carbon saturation point and one or more cycles are carried out at a temperature above the carbon saturation point. For example, in Example 1, the first cycle is carried out between 2480° F. and 2530° F., the second cycle is carried out between 2480° F. and 2530° F., the third cycle is carried out at 2453° F. and 2459° F., the fourth cycle is carried out between 2441° F. and 2450° F., the fifth cycle is carried out between 2406° F. and 2438° F., and the sixth cycle is carried out between 2406° F. and 2419° F. A cycle following an earlier cycle can have the identical temperature range as the earlier cycle, a partially overlapping temperature range with the earlier cycle, a temperature range above that of the earlier cycle, or a temperature cycle below that of the earlier cycle. Partially overlapping temperature ranges includes ranges where one temperature range falls within the limits of a second temperature range (e.g., 2406° F. to 2438° F. and 2406° F. to 2419° F.). Preferably, during an iterative cycling process, the degree to which the metal or alloy is saturated with carbon increases over the process.

Cycles of the present invention can vary in duration. The duration of a cycle can vary among cycles in a step. A cycle duration is, for example, about 2 minutes to about 90 minutes, about 3 minutes to about 67 minutes, about 5 minutes to about 45 minutes, about 8 minutes to about 30 minutes, about 10 minutes to about 20 minutes, about 14 minutes to about 18 minutes, about 7 minutes to about 9 minutes, about 13 minutes to about 15 minutes, about 17 minutes to about 19 minutes, about 28 minutes to about 32 minutes, or about 29 minutes to about 31 minutes.

A cycle can be symmetry or asymmetric. In a symmetric cycle, the period of increasing the metal or alloy temperature is equal to the period of decreasing the metal or alloy temperature. In an asymmetric cycle, the period of increasing the metal or alloy temperature is different than the period of decreasing the metal or alloy temperature. For an asymmetric cycle, the period of increasing the metal or alloy temperature can be longer than or shorter than the period of decreasing the metal or alloy temperature.

For example, in a cycle lasting about 7 minutes to about 9 minutes, the temperature can be increased for about 3 minutes and the temperature can be decreased for about 5 minutes. If the cycle lasts about 13 minutes to about 15 minutes, the temperature can be increased for about 7 minutes and the temperature can be decreased for about 7 minutes. If the cycle lasts about 17 minutes to about 19 minutes, the temperature can be increased for about 9 minutes and the temperature can be decreased for about 9 minutes. If the cycle lasts about 29 minutes to about 31 minutes, the temperature can be increased for about 15 minutes and the temperature can decreased for about 15 minutes.

The number of cycles in a step is generally an integer or half-integer value. For example, the number of cycles in a step can be one or more, one to forty, or one to twenty. The number of cycles can be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, or 40. Alternatively, the number of cycles in a step can be 0.5, 1.5, 2.5, 3.5, 4.5, 5.5, 6.5, 7.5, 8.5, 9.5, 10.5, 11.5, 12.5, 13.5, 14.5, 15.5, 16.5, 17.5, 18.5, 19.5, 20.5, 21.5, 22.5, 23.5, 24.5, 25.5, 26.5, 27.5, 28.5, 29.5, or 30.5. In a step comprising a half-integer or a non-integer quantity of cycles, either heating or cooling can occur first.

After the initial heating step, the temperature of a metal or an alloy is sufficiently high, such that the temperature is equal to or greater than the solidus temperature. The solidus temperature varies depending on the metal or the alloy, and the amount of carbon dissolved therein. The temperature at the end of Step (F.) of the third paragraph of the summary is typically about 900° F. to about 3000° F., but varies from metal to metal. For example, the temperature at the end of Step (F.) can be about 1932° F. to about 2032° F., about 1957° F. to about 2007° F., or about 1932° F. to about 2467° F. for copper; about 2368° F. to about 2468° F., about 2393° F. to about 2443° F., or about 2368° F. to about 2855° F. for nickel; about 2358° F. to about 2458° F. or about 2373° F. to about 2423° F., or about 2358° F. to about 2805° F. for cobalt; about 1932° F. to about 2032° F., about 1957° F. to about 2007° F., or about 1932° F. to about 2467° F. for a copper/gold/silver alloy; about 399° F. to about 499° F., about 424° F. to about 474° F., or about 399° F. to about 932° F. for a tin/lead/zinc alloy; about 399° F. to about 499° F., about 424° F. to about 474° F., or about 399° F. to 932° F. for a tin/sodium/potassium/magnesium alloy; about 2550° F. to about 2650° F., about 2575° F. to about 2625° F., or about 2550° F. to about 2905° F. for silicon; about 2058° F. to about 2158° F., about 2073° F. to about 2123° F., or about 2058° F. to about 2855° F. for iron; about 2058° F. to about 2158° F., about 2073° F. to about 2123° F., or about 2058° F. to about 2855° F. for an iron/vanadium/chromium/manganese alloy; or 2368° F. to about 2468° F., about 2393° F. to about 2443° F., or about 2368° F. to about 2855° F. for a nickel/tantalum/hafnium/tungsten alloy.

Inert gas or gases can be added during a step. Inert gases are chosen, independently, from the group consisting of argon, nitrogen, helium, neon, xenon, krypton, hydrogen, and mixtures thereof. When an inert gas is added during a step, the inert gas (or mixture thereof) can change from cycle-to-cycle or within a cycle

For purposes of the present invention, inert gases used for purging, particularly in the backspace of a reactor are generally considered separately from the other inert gases. Nitrogen is typically added continuously through a method of the present invention, irrespective of whether “inert gas” flow into the metal is started or stopped. In one example, a nitrogen flow is maintained throughout an entire method, such that a nitrogen pressure of about 0.4-0.6 psi, or about 0.5 psi is maintained.

At the end of the instant methods, the molten metal or alloy is cooled. The metal or alloy is cooled, at minimum, to a temperature below the solidus temperature. Preferably, the metal or alloy is cooled to room or ambient temperature. Such cooling can include gradual and/or rapid cooling steps. Gradual cooling typically includes cooling due to heat exchange with air or an inert gas over 1 to 72 hours, 2 to 50 hours, 3 to 30 hours, or 8 to 72 hours. Rapid cooling, also known as quenching, typically includes an initial cooling with air or an inert gas to below the solidus temperature, thereby forming a solid mass, and placing the solid mass into a bath comprising a suitable fluid such as tap water, distilled water, deionized water, other forms of water, inert gases (as defined above), liquid nitrogen or other suitable liquified gases, a thermally-stable oil (e.g., silicone oil) or organic coolant, and combinations thereof. The bath should contain a suitable quantity of liquid at a suitable temperature, such that the desired amount of cooling occurs.

Methods of the present invention are carried out in a suitable reactor. Suitable reactors are selected depending on the amount of metal or alloy to be processed, mode of heating, extent of heating (temperature) required, and the like. A preferred reactor in the present method is an induction furnace reactor, which is capable of operating in a frequency range of 0 kHz to about 10,000 kHz, 0 kHz to about 3,000 kHz, or 0 kHz to about 1,000 kHz. Reactors operating at lower frequencies are desirable for larger metal charges, such that a reactor operating at 0-3,000 kHz is generally suitable for 20 pound metal charges and a reactor operating at 0-1,000 kHz is generally suitable for 5000 pound metal charges.

Typically, reactors of the present method are lined with a suitable crucible. Crucibles are selected, in part, based on the amount of metal or alloy to be heated and the temperature of the method. Crucibles selected for the present method typically have a capacity from about five pounds to about five tons. One preferred crucible is comprised of 89.07% Al₂O₃, 10.37% SiO₂, 0.16% TiO₂, 0.15% Fe₂O₃, 0.03% CaO, 0.01% MgO, 0.02% Na₂O₃, and 0.02% K₂O, and has a 9″ outside diameter; a 7.75″ inside diameter, and a 14″ depth. A second preferred crucible is comprised of 99.68% Al₂O₃, 0.07% SiO₂, 0.08% Fe₂O₃, 0.04% CaO, and 0.12% Na₂O₃, and has a 4.5″ outside diameter, a 3.75″ inside diameter and a 10″ depth.

After being subjected to a process of the present invention, metals and alloys can be analyzed by a variety of techniques, including chemical and physical methods. A preferred analytical method is x-ray fluorescence spectrometry. X-ray fluorescence spectrometry is described in “X-Ray Fluorescence Spectrometry”, by George J. Havrilla in “Handbook of Instrumental Techniques for Analytical Chemistry,” Frank A. Settle, Ed., Prentice-Hall, Inc: 1997, which is incorporated herein by reference.

XRF spectrometry is a well-known and long-practiced method, which has been used to detect and quantify or semi-quantify the elemental composition (for elements with Z≧11) of solid and liquid samples. This technique benefits from minimal sample preparation, wide dynamic range, and being nondestructive. Typically, XRF data are not dependent on which dimension (e.g., axial or radial) of a sample was analyzed. Accuracy of less than 1% error can generally be achieved with XRF spectrometry, and the technique can have detection limits of parts per million.

XRF spectrometry first involves exciting an atom, such that an inner shell electron is ejected (e.g., the photoelectric effect). Upon ejection of an electron, an outer shell electron will “drop” down into the lower-energy position of the ejected inner shell electron. When the outer shell electron “drops” into the lower-energy inner shell, x-ray energy is released. Typically, an electron is ejected from the K, L, or M shell and is replaced by an electron from the L, M, or N shell. Because there are numerous combinations of ejections and replacements possible for any given element, x-rays of several energies are emitted during a typical XRF experiment. Therefore, each element in the Periodic Table has a standard pattern of x-ray emissions after being excited by a sufficiently energetic source, since each such element has its own characteristic electronic state. By matching a pattern of emitted x-ray energies to values found in tables, such as those on pages 10-233 to 10-271 of “Handbook of Chemistry and Physics, 73^(rd) Edition,” edited by D. R. Lide, CRC Press, 1992, which is incorporated herein by reference, one can identify which elements are present in a sample. In addition, the intensity of the emitted x-rays allows one to quantify the amount of an element in a sample.

There are two standard variations of the XRF technique. First, as an energy-dispersive method (EDXRF), the XRF technique uses a detector such as a Si(Li) detector, which is capable of simultaneously measuring the energy and intensity of x-ray photons from an array of elements. EDXRF is well-suited for rapid acquisition of data to determine gross elemental composition. Typically, the detection limits for EDXRF are in the range of tens to hundreds of parts-per-million. A wavelength-dispersive technique (WDXRF) is generally better-suited for analyses requiring high accuracy and precision. WDXRF uses a crystal to disperse emitted x-rays, based on Bragg's Law. Natural crystals, such as lithium fluoride and germanium, are commonly used for high-energy (short wavelength) x-rays, while synthetic crystals are commonly used for low-energy (longer wavelength) x-rays. Crystals are chosen, in part, to achieve desired resolution, so that x-rays of different energies are disperse to distinguishable 2θ angles. WDXRF can either measure x-rays sequentially, such that a WDXRF instrument will step through a range of 2θ angles in recording a spectrum, or there will be detectors positioned at multiple 2θ angles, allowing for more rapid analysis of a sample. Detectors for WDXRF commonly include gas ionization and scintillation detectors. A further description of the use WDXRF technique in the present invention can be found in Example 1. Results from EDXRF and results from WDXRF can be compared by determining the relationship between a 2θ angle and the wavelength of the corresponding x-ray (e.g., using Bragg's Law) and converting the wavelength into an energy (e.g., energy equals wavelength multiplied by Planck's constant).

Analysis of emitted x-rays can be carried out automatically or semi-automatically, such as by using a software package (e.g., UniQuant, which is sold by Omega Data Systems BV, Veldhoven, The Netherlands) for either EDXRF or WDXRF. UniQuant is used for standardless semi-quantitative to quantitative XRF analysis using the intensities measured by a sequential x-ray spectrometer. The software package unifies all types of samples into one analytical program. The UniQuant software program is highly effective for analyzing samples for which no standards are available. Sample preparation is usually minimal or not required at all. Samples can be of very different natures, sizes and shapes. Elements from fluorine or sodium up to uranium, or their oxide compounds, can be analyzed in samples such as a piece of glass, a screw, metal drillings, lubricating oil, loose fly ash powder, polymers, phosphoric acid, thin layers on a substrate, soil, paint, the year rings of trees, and, in general, those samples for which no standards are available. The reporting is in weight % along with an estimated error for each element.

In software packages, such as UniQuant, an XRF spectrum is composed of data channels. Each data channel corresponds to an energy range and contains information about the number of x-rays emitted at that energy. The data channels can be combined into one coherent plot to show the number or intensity of emitted x-rays versus energy or 2θ angle (the 2θ angle is related to the wavelength of an x-ray), such that the plot will show a series of peaks. An analysis of the peaks by one skilled in the art or the software package can identify the correspondence between the experimentally-determined peaks and the previously-determined peaks of individual elements. For an element, peak location (i.e., the centroid of the peak with respect to energy or 2θ angle), peak profile/shape, peak creation, and peak fluidity would be expected to be essentially the same, within experimental error, for any sample containing the element. If the same quantity of an element is present in two samples, intensity will also be essentially the same, excepting experimental error and matrix effects.

A typical software package is programmed to correlate certain data channels with the emitted x-rays of elements. Quantification of the intensity of emitted x-rays is accomplished by integrating the XRF spectrum over a number of data channels. Based on the measured intensities and the previously-compiled data on elements, the software package will integrate over all data channels, correlate the emitted x-ray intensities, and will then calculate the relative abundance or quantity of elements which appear to be present in a sample, based upon comparison to the standards. Ideally, the relative abundances will total 100% prior to normalization. However, for a variety of reasons, such as improper or insufficient calibration, the relative abundances will not total 100% prior to normalization. Another reason that the relative abundances of elements do not total 100% prior to normalization is that a portion of the XRF spectrum falls outside of the data channels that the software package correlates with an element (i.e., a portion of the XRF spectrum is not recognized as belonging to an element and is not included in the relative abundance calculation). In this case, the relative abundances will likely total less than 100% prior to normalization. Representative examples of relative abundance data are presented in Table 4, which includes the results of XRF analyses of the products of Examples 1-10, as processed by a Uniquant software package.

X-ray emission spectrometry (XES), a technique analogous to XRF, also provides electronic information about elements. In XES, a lower-energy source is used to eject electrons from a sample, such that only the surface (to several micrometers) of the sample is analyzed. Similar to XRF, a series of peaks is generated, which corresponds to outer shell electrons replacing ejected inner shell electrons. The peak shape, peak fluidity, peak creation, peak intensity, peak centroid, and peak profile are expected to be essentially the same, within experimental error and matrix effects, for two samples having the same composition.

A new composition of matter of the present invention can manifest itself as a transient, adjustable, or permanent change in energy and/or associated properties, as broadly defined. Property change can be exhibited as or comprise a change in: (1) structural atomic character (e.g., XES/XRF peak creation, peak fluidity, peak intensity, peak centroid, peak profile or shape as a function of material/sample orientation, atomic energy level(s), and TEM, STM, MFM scans); (2) electronic character (e.g., electron electromagnetic interactions, electromagnetic field position/orientation, energy gradients, Hall effect, voltage, capacitance, voltage decay rate, voltage gradient, voltage signature including slope of decay and/or change of slope decay, voltage magnitude, voltage orientation); (3) structural molecular or atomic character (e.g, SEM, TEM, STM, AFM, LFM, and MFM scans, optical microscopy images, and structural orientation, ordering, long range alignment/ordering, anisotropy); (4) physical constants (e.g., color, crystalline form, specific rotation, emissivity, melting point, boiling point, density, refractive index, solubility, hardness, surface tension, dielectric, magnetic susceptibility, coefficient of friction, x-ray wavelengths); (5) physical properties (e.g., mechanical, chemical, electrical, thermal, engineering, and the like); and, (6) other changes that differentiate naturally occurring materials from manufactured materials created by inducing a change in matter.

1. Structural Atomic Character

In the sections below, certain analyses have been conducted where a block of a manufactured product (e.g., a metal or an alloy) has been cut from a larger piece. In these analyses, the axial direction or an axial trace refers to a side of the block that was originally parallel to the side walls of a reactor. The radial direction or a radial trace refers to a side of the block that was originally parallel with the top or bottom of a reactor. A metal block can also contain micro- or macro-voids that can be analyzed.

FIG. 1A shows a non-contact, magnetic force microscopy image of natural copper, the control standard, and FIG. 1B shows a new composition of matter: manufactured copper, which is identified by an altered and aligned electromagnetic network. FIG. 2A shows a non-contact, magnetic force microscopy (MFM) scan and FIG. 2B shows a scanning tunneling microscopy (STM) scan. Individually, and from differing vantage points, these scans show the outline of the changed electromagnetic energy network. The MFM scan shows the radial trace while the STM scan shows the axial trace.

XES analysis of the control standard compared to the atomically altered (i.e., manufactured) state are shown in FIGS. 3A, 3B, 4A, and 4B. Manufactured copper in the axial direction exhibits similar composition to natural copper (i.e., 99.98%_(wt)), but radial scans exhibit new peaks in the region close to naturally occurring S, Cl, and K. The shifting centroid of the observed peaks from the natural species (i.e., S, Cl, K) confirm electronic change in the atomic state of the base element; as does the non-contact MFM void scan (compare FIG. 1B with FIG. 5A). Conventional chemical analysis performed using a LECO (IR) analyzer confirmed the absence of sulfur at XES lower detection limits. LECO analysis confirmed sulfur concentration at 7.8 ppm; this analysis was consistent with the manufacture's batch product analysis of 7.0 ppm S.

FIG. 5B compares the XES radial scan of manufactured copper to that of a void space within the same material. An underlying change in atomic character can be inferred from a dramatic change in signal count/intensity and a non-contact MFM of the void space (FIG. 5A). MFM evidence highlights the structure and its changed orientation and alignment compared to the control MFM (FIG. 1A).

High precision XRF imaging shows that manufactured copper has a K_(α) line in the vicinity of 110.7 degrees (the 2θ angle). Since 110.7 degrees is the location of natural sulfur's K_(α) line, this K_(α) line is referred to herein as a “sulfur-like” K_(α) line. This is the K_(α) line that would be expected if detectable quantities of sulfur were present; however, an IR LECO analysis of this sample showed that there was no sulfur was present (<10 ppm) in the sample. The presence of this line indicates an electronic structure change, which has shifted the two theta degree position of the K_(α) line compared to natural copper (FIGS. 6A and 6B). Several other figures indicate the presence of unexpected K_(α) lines for elements not present in the sample (e.g., FIG. 27 shows the presence of a significant aluminum-like K_(α) line for a sample containing 99.98% copper). FIG. 7 shows an increase in signal intensity dependent upon which side of a homogeneous block of sample was analyzed, as well as a shifting K_(α) centroid. These data demonstrate microscopically the bulk anisotropy later identified in the manufactured sample as does the MFM scans (FIGS. 1B and 5A).

2. Electronic Character

Manipulation of the electrodynamic components affecting the orientation of a manufactured metal's or alloy's electromagnetic field can enable the observance of a Hall voltage (V_(H)). Manipulation of the electrodynamic components enables intensification of electromagnetic field affording charge concentration on the surface of the atoms within the bulk as opposed to the bulk surface of the bath. Properties that reflect field repositioning can include changing capacitance and voltage decay rate (FIG. 8) and voltage gradients (FIG. 9) within a conducting bulk media.

FIG. 10 shows the V_(H) observed in a copper-nickel alloy. Voltage decay exhibited two distinct decay rates, indicative of two controlling mechanisms. A positive voltage signature with a positive capacitance decay (i.e., capacitance accumulation) is shown in FIG. 11.

Control and manipulation of the charge signature (e.g., V_(H) profile, capacitance slope, voltage slope) provides evidence of the alteration, and manipulation of the underlying electronic state. FIG. 12 shows a positive voltage signature and a positive capacitance decay. Additionally, the voltage decay profile has changed: one profile has a negative slope while the other has a neutral slope. Further change in the electronic structure enables the slope of the second voltage decay profile to become positive (FIG. 13); note also the change in slope of capacitance decay. The metal system shown in FIG. 14 has an electronic structure change that result in a nearly neutral decay in voltage and capacitance. Measurements were repeated four times. FIG. 15 shows that the voltage can actually become negative, indicating that the orientation can also be manipulated. FIG. 16 shows the phenomena can be observed under pressure. Table 1 is an XRF analysis using a Uniquant software package that shows a multiplicity of energetically contiguous X-ray atomic energy levels. One energetically contiguous series is represented by Sm, Eu, Gd, Th; the other is represented by P, S, So (i.e., sulfur as an oxide), Cl, and Ar. Table 2 is an XRF analysis using a Uniquant software package that shows an energetically contiguous series as Al, Si, P, S, So (i.e., sulfur as an oxide), Cl, Ar, K, and Ca. Table 3 represents an experiment that utilized the same starting material as Tables 1 and 2, however, the reported amount or abundance of copper after processing differs from the other tables. The differing relative abundances of elements observed in Tables 1-3 are believed to correspond to the unexpected peaks seen in many of the XRF plots.

3. Structural Molecular/Atomic Character

New compositions of matter can be electronically modified to induce long range ordering/alignment. In one new composition of matter, long range ordering was induced in oxygen-free high conductivity (OFHC) copper. Optical microscopy and SEM imaging of the material verifies the degree and extent of long range ordering achieved (FIGS. 17A, 17B, 17C, 18A, 18B, and 18C). Under similar electronic conditions, long range ordering was induced in high purity (99.99%_(wt)) nickel. FIGS. 19A, 19B, 20A, and 20B show the optical microscopy imaging of the manufactured nickel material. A comparison of alignment is shown in-run, at two different points during processing, which highlights the adjustability of the altered electronic state of the manufactured nickel.

Extensive atomic force microscopy and non-contact MFM imaging of electronically altered OFHC copper shows views of structural configurations from a different perspective (FIGS. 21A, 21B, 21C, 22A, 22B, and 22C). Non-contact MFM imaging shows clear pattern repetition and intensity of the manufactured copper when compared to the natural copper. The manufactured copper represents a new composition of matter derived from natural copper, and the manufactured copper exhibits anisotropic behavior.

4. Physical Constants

In one sequence of new compositions of matter, color changes in OFHC copper were induced. The variation in color over four (4) new matter compositions ranged from black (two intensities) to copper (2 intensities) to gold (one intensity) to silver (one intensity). While not being bound by theory, the alteration of copper's electronic state along the continuum enables the new composition of matter's color to be adjusted along the continuum.

In another sequence of new compositions of matter, changes in the hardness of OFHC copper were induced. The variation in diamond pyramid hardness between different manufactured copper samples ranged from about 25 to 90 (or 3 to 9 times higher than natural copper). Hardness change was anisotropic.

In another new composition of matter, magnetism was induced in a high purity, non-magnetic metal copper (e.g., 99.98%_(wt)) in its elemental form (FIGS. 23A and 23B).

5. Physical Properties

In one sequence of new compositions of matter, ductility changes were induced in a high purity, ductile copper (99.98%_(wt)) in its elemental form. The variation in the engineering physical property of ductility ranged from brittle to semi-ductile to ductile to extremely ductile over four (4) new matter compositions.

In one new composition of matter, the electrical reactance was increased approximately 3% above that of natural copper over the frequency range of 0 Hz to 100 kHz. In another new composition of matter, electrical susceptance was increased approximately 20% above 99.98%_(wt) copper of the same chemical composition (i.e., the copper in its natural state). In another new composition of matter, electrical susceptance was decreased approximately 25% below 99.98%_(wt) copper of the same chemical composition (i.e., the copper in its natural state). Electrical susceptance for these new matter compositions compared to the control standard (the material in its natural state) is shown in FIG. 24.

6. Additional Differentiations

In one sequence of new compositions of matter, which all used the same raw materials, consumables, utilities, and materials of construction, the sum of element concentrations identified by XRF analysis varied considerably. Variations in elemental abundance determined by XRF Uniquant prior to normalization over three (3) new matter compositions were 99.5%_(wt) (Table 3), 96.0%_(wt) (Table 2), and 90.6%_(wt) (Table 1). The apparent loss of matter between the recognized elemental structures and the manufactured elemental structures differentiates naturally occurring materials from materials with modified electronic structures (i.e., a new composition of matter).

While not being bound by theory, Applicant believes the conservation of energy requires that all mass, independent of magnitude and/or configuration, character, and/or dimension can be characterized by the allowed set of mathematical poles (defined as the operation zurn) and further characterized by the set of mathematical poles coalesced (defined as the isozurn value). An adjustment or manipulation of the zurn invokes a change in the isozurn value to a value different than its naturally occurring value, and accounts for the contribution of its rest state value, thereby modifying the electronic structure that defines the natural state. A change in the isozurn value to a value different than that which specifies the natural state denotes a change in the underlying electronic state of the specified species.

A change in the isozurn value is typically noted at the subatomic, atomic, or molecular level. While not being bound by theory, the complexity of energy interactions is believed to often impede single variable isolation. In these cases, a change in the electronic state of the specified species typically manifests itself as a change in a property value(s) from the naturally occurring state (e.g., the unaltered entropic driven ground state). Typical changes denoting a change in property value, which depart from the property value specifying its naturally occurring state, dictate a change in the isozurn value of that state.

EXEMPLIFICATION Example 1 Experimental Procedure for Copper Run 14-01-01

A cylindrical alumina-based crucible (99.68% Al₂O₃, 0.07% SiO₂, 0.08% Fe₂O₃, 0.04% CaO, 0.12% Na₂O₃; 4.5″ O.D.×3.75″ I.D.×10″ depth) of a 100 pound induction furnace reactor (Inductotherm) fitted with a 75-30R Powertrak power supply was charged with 2500 g copper (99.98% purity) through its charging port. The reactor was fitted with a graphite cap and a ceramic liner (i.e., the crucible, from Engineering Ceramics). During the entire procedure, a slight positive pressure of nitrogen (˜0.5 psi) was maintained in the reactor using a continuous backspace purge. The reactor was heated to the metal charge liquidus point plus 300° F., at a rate no greater than 300° F./hour, as limited by the integrity of the crucible. The induction furnace operated in the frequency range of 0 kHz to 3000 kHz, with frequency determined by a temperature-controlled feedback loop implementing an Omega Model CN300 temperature controller. Upon reaching 2300° F., the reactor was charged with an additional 2143 g copper over an hour.

The temperature was again increased to 2462° F. again using a rate no greater than 300° F./hour. When this temperature was reached, graphite saturation assemblies (⅜″ OD, 36″ long high purity (<5 ppm impurities) graphite rods) were inserted to the bottom of the copper charge through ports located in the top plate. The copper was held at 2462° F. for 4 hours. Every 30 minutes during the hold period, an attempt was made to lower the graphite saturation assemblies as dissolution occurred. As the copper became saturated with carbon, the graphite saturation assemblies were consumed. After the 4 hour hold period was complete, the graphite saturation assemblies were removed.

The reactor temperature was increased to 2480° F. over 7 minutes. The temperature was then varied between 2480° F. and 2530° F. for 15 cycles. Each cycle consisted of raising the temperature continuously over 7 minutes and lowering the temperature continuously over 7 minutes. After the 15 cycles were completed, a gas addition lance was lowered into the molten metal to a position approximately 2″ from the bottom of the reactor and a 0.15 L/min flow of argon was begun. The temperature of the copper was varied over another 5 cycles between 2480° F. and 2530° F.

After the fifth cycle, the reactor temperature was lowered to 2462° F. over a 10 minute period with continued argon addition. The graphite saturation assemblies were reinstalled in the copper and remained there for 1 hour. The graphite saturation assemblies were removed.

The reactor temperature was lowered to 2459° F. over 5 minutes. The reactor was held at this temperature for 5 minutes with continued argon addition. The temperature was then varied between 2459° F. and 2453° F. over 20 cycles. Each cycle consisted of lowering the temperature continuously over 9 minutes and raising the temperature continuously over 9 minutes. The argon addition ceased after completion of the 20 cycles.

The reactor temperature was lowered to 2450° F. over 5 minutes. The temperature was varied between 2450° F. and 2441° F. over 4½ cycles. Each cycle consisted of lowering the temperature continuously over 5 minutes and raising the temperature continuously over 3 minutes. In addition, while raising the temperature, a 0.15 L/min flow of argon was added, and while lowering the temperature, a 0.15 L/min flow of nitrogen was added.

The reactor temperature was lowered to 2438° F. over 5 minutes. The temperature was varied between 2438° F. and 2406° F. for 15.5 cycles. Each cycle consisted of lowering the temperature continuously over 15 minutes and raising the temperature continuously over 15 minutes. In addition, while raising the temperature, a 0.15 L/min flow of argon was added, and while lowering the temperature, a 0.15 L/min flow of nitrogen was added. All gas addition, except for the purge of nitrogen ceased after the 15.5 cycles were completed.

The temperature was varied between 2406° F. and 2419° F. for one cycle. The cycle consisted of raising the temperature continuously over 15 minutes and lowering the temperature continuously over 15 minutes. The gas addition lance was removed

The reactor temperature was cooled by lowering the induction furnace power to 1 kW or less as the ingot cooled. The copper was then cooled to approximately ambient temperature in water.

Analytical Protocols

X-Ray Fluorescence

An ARL 8410 XRF was used to analyze each of the sample ingots. An ARL 8410 is a sequential wavelength dispersive spectrometer (WDS). Specific emission lines are used to determine the presence or absence, and the concentrations of various elements. Each characteristic x-ray line is measured in sequence by the instrument by controlling the instrument geometry.

FIG. 62 shows the general configuration of the ARL 8410 spectrometer. The WDS spectrometer relies on the fundamentals of x-ray diffraction, when x-ray fluorescence occurs when matter is bombarded by a stream of high-energy incident x-ray photons. When the incident X-radiation strikes the sample, the incident x-rays may be absorbed, scattered, or transmitted for the measurement of the fluorescent yield.

The ARL 8410 utilizes an end-window rhodium (Rh) x-ray tube. The end-window is composed of Be, and holds the tube at high vacuum. The filaments are heated giving off electrons by thermoionic emission. This beam of electrons then bombards the target Rh anode across a 10-70 keV voltage potential. Thus, primary x-rays are produced during the collision. The emitted x-ray spectrum consists of (1) “Continuum” or “Bremstrahlung” radiation, (2) Characteristic x-ray lines of the target material (e.g., K and L series), and (3) Characteristic lines from any contaminants. Thus, the primary spectrum appears as a series of sharp intense peaks arrayed over a broad hump of continuum radiation. The ARL is equipped with and uses two types of photon detectors, the Flow Proportional Counter (FPC) and the Scintillation Counter (SC).

The manufactured metal samples are prepared by cutting a cube shape (approximately 1.1875″) from the center of the cooled ingot. An axial edge and a radial edge are then denoted. To provide a smooth surface for analysis, the axial and radial faces are sequentially polished. The sample faces are sanded to 400 grit, then a polishing wheel is employed with 600 grit paper. Finally, a ≦1 μm polishing compound completes the smoothing process. The sample is then cleaned with iso-propyl alcohol and placed in a sample cassette/holder. The sample holder is then loaded into the XRF.

The orientation of the detector crystal with respect to the sample and the photon detector is controlled synchronously such that characteristic x-ray lines can be accurately measured. A sequential measurement consists of positioning the diffraction crystal at a given theta (diffraction angle) and the detector at two-theta and counting for a given period of time. The crystal and detector are then rotated to a different angle for the next characteristic x-ray line.

Uniquant Version 2 software, developed by Omega Data Systems is used to control the crystal and detector placement and provides the data reduction algorithms for each analytical protocol. The sample results include an elemental composition list along with the associated concentrations for each sample.

Measurement of Grain Sizes

When the grain sizes exceeded the size discernible with the human eye, the grain size (average span distance) was measured using a micrometer. When the grain sizes were not discernible via the naked eye, standard acid etching was performed and then optical microscopy was utilized to measure and characterize the grain.

Measurement of Magnetism

The magnetic properties of the manufactured ingots were tested via three methods.

Magnetic Attraction: An ⅛″ diameter neodymium iron boron magnet was scanned consistently and uniformly across the surface of the ingot to detect areas of attraction. Areas of attraction were then noted at specific sites on the surface.

Attraction to Iron: The attraction of iron filings to specific points on the ingot were quantified by enumerating the number of filings retained on the ingot surface in a vertical or upside-down orientation.

Gauss Measurement: The magnetic behavior of various points on the ingot were quantified via the use of a F. W. Bell 4048 Gauss meter.

Measurement of Chemical Reactivity

The manufactured ingots were subjected to various chlorine ligands, including NaCl, NaOCl, HCl, and chlorinated organics to semi-quantitatively access their reactivity to ligated chlorine. The formation of reaction products was recorded, then reaction products were removed from the reaction site, weighed and elemental composition verified via XRF.

The manufactured copper exhibited large grain sizes and different coloration on each grain, which caused the surface to appear iridescent. The axial (top) face of the ingot appeared glassy, while the sides were metallic in appearance (due to anisotropic behavior). The color on both the axial and radial surfaces mimicked that of natural copper (i.e., not the intense reds or dark browns observed in other manufactured coppers, for example, Examples 11-14). On the axial surface, unique demarcations were observed. The ingot had some internal void areas, which were open to the top surface. No unexpected magnetic activity or chemical reactivity were recorded.

The reactor was fitted with a graphite cap with a ceramic liner (i.e. the crucible, from Engineering Ceramics). During the entire procedure, a slight positive pressure of nitrogen (˜0.5 psi) was maintained in the reactor using a continuous backspace purge. The reactor was heated to the metal charge liquidus point, over a rate no greater than 300° F./hour, as limited by the integrity of the crucible. The induction furnace operated in a frequency range of 0 kHz to 3000 kHz, with frequency determined by a temperature-controlled feedback loop implementing an Omega Model CA 300 temperature controller. Upon reaching 2800° F., the reactor was charged with an additional, 2700 g nickel over an hour.

When this temperature was reached, graphite saturation assemblies (⅜″ OD, 36″ long high purity [<5 ppm impurities] graphite rods) were inserted to the bottom of the nickel charge through ports located in the top plate. The nickel was held at 2850° F. for 4 hours. Every 30 minutes during the hold period, an attempt was made to lower the graphite saturation assemblies as dissolution occurred. As the nickel became saturated with carbon, the graphite saturation assemblies were consumed. After the 4 hour hold period was complete, the graphite saturation assemblies were removed.

Each cycle consisted of lowering the temperature continuously over 7 minutes and raising the temperature continuously over 7 minutes. After the 15 cycles were completed, a gas addition lance was lowered and a 0.15 L/min flow of argon was begun. The temperature of the nickel was varied over another 5 cycles between 2950° F. and 3256° F.

The manufactured nickel retained a large amount of refractory on its exterior surface after retrieval from the reactor. The retained refractory was attributed to either surface attraction or reaction with the high content of Al₂O₃ in the refractory. The ingot did not crack with handling, but did have an internal void. The visible radial surface appeared duller in than the axial (top) face, again demonstrating anisotropic physical properties. The ingot demonstrated no unexpected chemical reactivity after removal from the reaction system.

The reactor was fitted with a graphite cap with a ceramic liner (i.e. the crucible, from Engineering Ceramics). During the entire procedure, a slight positive pressure of nitrogen (˜0.5 psi) was maintained in the reactor using a continuous backspace purge. The reactor was heated to the metal charge liquidus point plus 300° F., at a rate no greater than 300° F./hour, as limited by the integrity of the crucible. The induction furnace operated in the frequency range of 0 kHz to 3000 kHz, with frequency determined by a temperature-controlled feedback loop implementing an Omega Model CN300 temperature controller. Upon reaching 900° F., the reactor was charged with an additional 2120 g Sn over an hour.

The temperature was again increased to 932° F. again using a rate no greater than 300° F./hour. When this temperature was reached, graphite saturation assemblies (⅜″ OD, 36″ long high purity (<5 ppm impurities) graphite rods) were inserted to the bottom of the Sn/Na/K/Mg charge through ports located in the top plate. The Sn/Na/K/Mg alloy was held at 932° F. for 4 hours. Every 30 minutes during the hold period, an attempt was made to lower the graphite saturation assemblies as dissolution occurred. As the Sn/Na/K/Mg alloy became saturated with carbon, the graphite saturation assemblies were consumed. After the 4 hour hold period was complete, the graphite saturation assemblies were removed.

The reactor temperature was increased to 968° F. over 7 minutes. The temperature was then varied between 942° F. and 968° F. for 15 cycles. Each cycle consisted of lowering the temperature continuously over 7 minutes and raising the temperature continuously over 7 minutes. After the 15 cycles were completed, a gas addition lance was lowered into the molten metal to a position approximately 2″ from the bottom of the reactor and a 0.15 L/min flow of argon was begun. The temperature of the Sn/Na/K/Mg alloy was varied over another 5 cycles between 942° F. and 968° F.

A cylindrical alumina-based crucible (89.07% Al₂O₃, 10.37% SiO₂, 0.16% TiO₂, 0.15% Fe₂O₃, 0.03% CaO, 0.01% MgO, 0.02% Na₂O₃, 0.02% K₂O; 9″ O.D.×7.75″ I.D.×14″ depth) of a 100 pound induction furnace reactor supplied by Inductotherm, fitted with a 75-30R Powertrak power supply, was charged with 100 pounds copper (99.98% purity) through its charging port. During the entire procedure, a slight positive pressure of nitrogen (˜0.5 psi) was maintained in the reactor using a continuous backspace purge. The reactor was heated to the metal charge liquidus point plus 300° F., at a rate no greater than 300° F./hour, as limited by the integrity of the crucible. The induction furnace operated in the frequency range of 0 kHz to 3000 kHz, with frequency determined by a temperature-controlled feedback loop implementing an Omega Model CN300 temperature controller.

The temperature was again increased to 2462° F. again using a rate no greater than 300° F./hour. When this temperature was reached, graphite saturation assemblies (⅜″ OD, 36″ long high purity (<5 ppm impurities) graphite rods) were inserted to the bottom of the copper charge through ports located in the top plate. The copper was held at 2462° F. for 4 hours. Every 30 minutes during the hold period, an attempt was made to lower the graphite saturation assemblies as dissolution occurred. As the copper became saturated with carbon, the graphite saturation assemblies were consumed. After the 4 hour hold period was complete, the graphite saturation assemblies were removed.

The reactor temperature was increased to 2480° F. over 7 minutes. The temperature was then varied between 2480° F. and 2530° F. for 15 cycles. Each cycle consisted of raising the temperature continuously over 7 minutes and lowering the temperature continuously over 7 minutes. After the 15 cycles were completed, a gas addition lance was lowered into the molten metal to a position approximately 2″ from the bottom of the reactor and a 1.5 L/min flow of argon was begun. The temperature of the copper was varied over another 5 cycles between 2480° F. and 2530° F.

After the fifth cycle, the reactor temperature was lowered to 2462° F. over a 10 minute period with continued argon addition. The graphite saturation assemblies were reinstalled in the copper and remained there for 1 hour. The graphite saturation assemblies were removed.

The reactor temperature was lowered to 2459° F. over 5 minutes. The reactor was held at this temperature for 5 minutes with continued argon addition. The temperature was then varied between 2459° F. and 2453° F. over 20 cycles. Each cycle consisted of lowering the temperature continuously over 9 minutes and raising the temperature continuously over 9 minutes. The argon addition ceased after completion of the 20 cycles.

The reactor temperature was lowered to 2450° F. over 5 minutes. The temperature was varied between 2450° F. and 2441° F. over 4½ cycles. Each cycle consisted of lowering the temperature continuously over 5 minutes and raising the temperature continuously over 3 minutes. In addition, while raising the temperature, a 1.5 L/min flow of argon was added, and while lowering the temperature, a 1.5 L/min flow of nitrogen was added.

The reactor temperature was lowered to 2438° F. over 5 minutes. The temperature was varied between 2438° F. and 2406° F. for 15.5 cycles. Each cycle consisted of lowering the temperature continuously over 15 minutes and raising the temperature continuously over 15 minutes. In addition, while raising the temperature, a 1.5 L/min flow of argon was added, and while lowering the temperature, a 1.5 L/min flow of nitrogen was added. All gas addition, except for the purge of nitrogen ceased after the 15.5 cycles were completed.

The temperature was varied between 2406° F. and 2419° F. for one cycle. The cycle consisted of raising the temperature continuously over 15 minutes and lowering the temperature continuously over 15 minutes. The gas addition lance was removed.

The reactor temperature was rapidly cooled by quenching in water, so that the copper solidified into an ingot.

Analytical Protocols

XRF, grain size, magnetism, and chemical reactivity measurements were carried out by the procedures described in Example 1.

Analytical Results

Summary data showing the apparent elemental composition of the product of Example 11 is shown in Tables 32-33, as was measured by an XRF analysis using a Uniquant software package. The apparent elemental composition of the product varies by position, which is indicated in each table.

Immediately after the method described above was completed, multiple discrete magnetic spots attracted by a ⅛″ diameter neodymium iron boron magnet were observed in a sinusoidal pattern. The ingot exhibited point attraction to iron filings at reduced temperatures at or near 77 K. Over days to months, the strength of the magnetic attraction decreased on a fraction of the locations exhibiting magnetic attraction or attraction to iron filings.

Various forms of ligated chlorine (e.g., HCl and MCl, where M is a metal as defined above) readily reacted with the manufactured copper form yielding product distributions distinguishable from natural copper, thereby demonstrating a change in chemical reactivity. This reactivity increased over time.

Extremely large grain sizes (i.e., greater than 1″) were observed, which is uncharacteristic and previously unreported in natural copper systems (typically, copper grains sizes are 10-100 μm). Unique changes in coloration were observed with the crossing of grain boundaries; however, the overall coloration mimicked natural copper.

This manufactured copper system demonstrated an ability to change color (i.e., visible light spectrum emission) dependent upon electromagnetic stimulation. The color of the top, glassy surface of an ingot changed under different lighting conditions. While the (radial) side of the ingot was a matte pink color, the top of the ingot (axial face) has a glassy color, which can vary from intense burgundy to golden bronze to burnished orange. These differences in appearance reflect the anisotropy detected via the XRFs.

The radial surface of the ingot was covered with magnetically active spots. The magnetism of the ingot decreased over time. Altered chemical reactivity, particularly with respect to ligated chlorine, was observed on axial surfaces. The chemical reactivity increased over time. Radial surfaces appeared unaffected and were free from refractory (material from the crucible).

The manufactured copper demonstrated an ability to change color (i.e., visible light spectrum emission), dependant upon electromagnetic stimulation. The top (axial face) of the ingot can vary from intense burgundy to a deep golden orange. Additionally, the appearance and color of this ingot reflect the anisotropy detected via the XRF scans. The radial (side) face appears like burnished copper, while the axial (top) face has a glassy appearance.

On the bottom and side faces, each of the grain boundaries is clearly delineated. Each of the grains appears to have a different color, giving the exterior of the ingot an iridescent appears. The ingot did not have an internal void, as ingots of previous examples did. Additionally, the ingot did not exhibit the extensive magnetic activity observed in Examples 11 and 12. The ingot retained an extensive amount of refractory upon retrieval from the reactor.

While this invention has been particularly shown and described with references to preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention encompassed by the appended claims.
